<p>This error message can appear if there are files remaining on the system from a previous F-Secure product installation. Before retrying the installation, it is recommended to do a "complete removal" of previous F-Secure products by running the F-Secure Uninstallation Tool. <br><br>The F-Secure Uninstallation Tools are available from <a rel="nofollow" href="https://www.f-secure.com/en/business/support-and-downloads/support-tools">https://www.f-secure.com/en/business/support-and-downloads/support-tools </a><br> <br><b>Note:</b> Please take note of the product version you are installing. Older and newer product versions use different uninstallation tools.<br><br>After running the uninstallation tool and completing the uninstall process, best practice is to restart the computer then complete re-installation steps using the latest installer / latest version. For servers, it is recommended to perform the steps during off-peak hours. </p>
